groundwater characterization News

Synopsis: Environmental practitioners are often constrained by rigorous time and monetary constraints, which can lead to the collection of limited data sets and decisions made based on an inadequate understanding of site conditions. To facilitate effective site assessments in British Columbia, the BC Ministry of Environment recently released a new guidance document, "Technical Guidance #8", for ...

At this year’s Symposium, attendees were thoroughly intrigued when Guy Patrick described the new guidance document for groundwater site characterization in B.C. The response was immensely positive and it is clear that Guy is setting the bar to increase the level of competency and accountability for groundwater monitoring and remediation applications. This is a real step forward for the ...

Two short courses offered by the National Ground Water Association are slated to take place in Denver, Colorado, next month. “Site Characterization: The Groundwater System” takes place April 26, while “Fundamentals of Groundwater Geochemistry” is scheduled for April 26-27. Designed for those involved with groundwater availability, monitoring, cleanup, and modeling ...

Chlorinated solvents have been used extensively in industry and are common groundwater contaminants. Their limited aqueous solubility often leads to the presence of dense non-aqueous phase liquid (DNAPL) source zones, which may persist due to mass transfer limitations from the DNAPL to groundwater. While recent research effort has been directed to the development of effective source zone ...

Design is a traditional task common to all engineering fields although most engineers do not have to deal with the heterogeneous properties of materials as is the case in site remediation, mining, geotechnical engineering, etc. A structural engineer can specify properties of steel or reinforced concrete and an electronics engineer can specify the physical properties of transistors, ...

In an initiative supported by EM, Los Alamos National Laboratory's Corrective Actions Program is addressing high explosive contamination in surface water and groundwater at a location this summer in the forests ...

The US Environmental Protection Agency (EPA) announced in late 2016 that 1,4-dioxane was included on the list of the first 10 chemicals slated to receive safety reviews under Toxic Substances Control Act (TSCA) reform. Making the TSCA “Top 10” highlights concerns over 1,4-dioxane, a probable carcinogen commonly detected in groundwater due to its widespread use as a solvent and solvent ...

The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

The National Ground Water Association is offering the short course, “Monitored Natural Attenuation: Mechanisms, Site Characterization, Evaluation, and Monitoring,” November 3-4 in Denver, Colorado.This course provides the conceptual and technical background necessary to evaluate natural attenuation mechanisms and their interaction with source and transport processes at sites with organic and ...

The call for abstracts is now open for the NGWA Conference on Hydrogeophysics and Deep Groundwater that is taking place in March 2017. Abstracts are being sought for the NGWA Conference on Hydrogeophysics and Deep Groundwater in the following two tracks and are due October 31, 2016. Track 1 — Applications of Hydrogeophysics to Groundwater Characterization, ...

This guide refers to ASTM methods by which soil, rock, and ground water conditions may be determined. The objective of the investigation should be to identify and locate, both horizontally and vertically, significant soil and rock types and ground water ...

Although the stimulation phase of the Newberry EGS Demonstration has come to a close, field work continues throughout the winter months on the volcano (brrr!). We’re currently collecting and analyzing groundwater samples in order to monitor any changes in the local groundwater system. This work is intended to make sure thestimulation hasn’t affected the quality of the groundwater high ...

The gasoline additive methyl tert-butyl ether (MTBE) is widespread in New Hampshire's ground water, particularly in four counties -- Rockingham, Strafford, Hillsborough and Merrimack. Ground water from these counties was more likely to contain MTBE than were samples from the rest of the state. Across the state, however, the MTBE concentrations were significantly below the state drinking water ...

The National Ground Water Association has opened a call for abstracts for the 2013 NGWA Summit — The National and International Conference on Groundwater, which will be featuring Charles Fishman, New York Times bestselling author of The Big Thirst, as the keynote speaker. To be held in San Antonio, Texas, April 28-May 2, the annual NGWA Summit, now in its ninth year, is a highly ...

Nitrate is the most common chemical contaminant in the world’s ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, ...

“Introduction to the Phytoremediation of Common Groundwater Contaminants,” a one-hour Webinar presented by the National Ground Water Association, will take place June 5, 2012 at 1 p.m. ET. Attendees will learn how trees can remediate many common groundwater contamination problems during this online presentation by Dr. James E. Landmeyer, a research hydrologist with the U.S. Geological ...

Andrea Croskrey, PG, from the Texas Water Development Board will give the keynote presentation, "Mapping Brackish Aquifers: Future Water Resources," at the NGWA Conference on Hydrogeophysics and Deep Groundwater taking place March 20-21, 2017 in Denver, Colorado. Croskrey has been mapping brackish aquifers in Texas as a member of the Brackish Resources Aquifer ...

The conference, Groundwater Monitoring: Design, Analysis, Communication, and Integration with Decision Making, will be held February 25-26, 2009 in Anaheim, California. Groundwater is a major component of the Nation’s water supply, and groundwater monitoring is an essential tool for characterizing and managing this vital resource. The goal of this conference, organized by the Groundwater ...

The National Ground Water Association's 2008 Ground Water Summit taking place March 30-April 3 in Memphis, Tennessee, features 20 sessions covering the latest in ground water science, technology, and ground water policy. This fourth annual Ground Water Summit brings together local, national, and international science partners to exchange information on scientific, policy, and regulatory issues ...
